Hager Hinge 175241D Spring Hinge 4x4 Steel Dull Black

Product Description

The HAGER HINGE 175241D is a full mortise residential spring hinge designed for interior door applications where controlled, self-closing action is required. Constructed from steel with a dull black finish, this hinge measures 4 inches x 4 inches with a 5/8-inch radius corner profile. The spring mechanism provides consistent door return without the need for a separate door closer. It is installed by finish carpenters, general contractors, and experienced door hardware tradespeople working on residential projects.

The 175241D is suited for residential interior doors requiring a self-closing function. The full mortise design means both the door and frame must be routed to accept the leaf, making it appropriate for new construction and replacement work where proper mortise cuts can be made. The dull black finish integrates with dark hardware schemes common in modern residential and light commercial interior applications.

Installation Notes

Installation requires mortise cuts in both the door edge and the door frame jamb to accept each leaf flush. A licensed finish carpenter or experienced door hardware installer should perform the mortise routing using a router or sharp chisels before seating the hinge. De-energize any electronic door hardware and ensure the door is fully removed from the opening before beginning work. Note that this hinge must be ordered in multiples of 2.
